linear functions that satisfies the given conditions:
f(0)= 2, f(9)=5
-----
f(0) = 2 tells you the y-intercept is 2
---
Equation:
y = mx + 2
---
Use (9,5) to solve for "m":
5 = m*9 + 2
9m = 3
m = 1/3
---------------------------
Equations:
y = (1/3)x + 2

If , then the point is on the graph of the function. Likewise if , then the point is on the graph of the function.

Now that you have two points, use the two-point form of the equation of a line to write your equation.
